HOUSTONIA WWTP - Secondary Treatment Plant in Houstonia, Missouri

HOUSTONIA WWTP is a municipal wastewater treatment facility located in Houstonia, Pettis County, Missouri. The plant serves a small population of 220 residents, reflecting its role in a rural community. It operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level for small communities in the United States. Its designed capacity is 151.42 thousand cubic meters per year, with an actual discharge volume of 75.71 thousand cubic meters per year, indicating operational headroom. The facility is situated inland, far from coastal waters, reducing direct marine impact. The treated effluent is discharged into a local waterway that ultimately drains into the Missouri River watershed. The Missouri River flows into the Mississippi River, which empties into the Gulf of Mexico. This downstream connection highlights the plant's role in protecting water quality within a major continental drainage basin.

The plant discharges into a tributary of the Missouri River, which flows into the Mississippi River and eventually reaches the Gulf of Mexico. The watershed supports diverse aquatic life and provides habitat for migratory fish species. As a small inland facility, its environmental impact is localized, but it contributes to the overall health of the Mississippi River basin, which is ecologically significant for nutrient management and biodiversity.
